Dead Man's Switch + USB Kill Switch for Linux - Open source defensive security project

Project Overview

Sharing a project I've been building for the community: a defensive security toolkit for Linux focused on physical server protection.

Features

It includes:

• USB kill switch - if the device is unplugged, LUKS keys are wiped and the system reboots
• Dead man's switch - no heartbeat in 24h triggers wipe and reboot
• Web-based manual kill switch with token authentication
• USBGuard-based USB device control via web UI

Designed to run on a private network (Tailscale), with Discord notifications.
